Centurion Timed Delay Bolt

Designed to provide a time delay after machine switch off prior to the guard being able to be opened
When the thumb wheel is manually rotated the interlock shaft is withdrawn, isolating the positive break safety contacts, removing the power to machinery
Only when completely withdrawn can equipment be accessed, typically taking 15-20 seconds
2N/C 1 N/O contacts, make-before-break
IP66 ingress protection
Simple operation & installation

Allen Bradley Guardmaster Safety Interlock Switch

The Allen Bradley Guardmaster centurion safety interlock switch has 2NC/1NO contacts. It has a voltage rating of 500VAC and 250VDC. This switch locks the guard closed until the operator manually rotates the thumbwheel, retracting the shaft from the guard door. The action of retracting the shaft initiates 2 functions it isolates the power to the machine when the guard is open and due to the operating principle, it gives up to 20 seconds delay before the guard can be opened. Alternative styles with longer shafts can increase the time delay by as much as 50%. It is ideal for use on simple machines with short, constant running downtimes. It is important to install and operate the unit correctly to ensure that the retractable shaft is not extended when the guard is open.
